Introduction

Japan Meteorological Agency (JMA) offers a GISC and 7 DCPCs.

RTH Tokyo/MTN centre (CBS) Meteorological Satellite Centre (CBS/WWW,WSP) RSMC on tropical cyclones (CBS) RSMC on data processing and forecasting system (CBS) RSMC on atmospheric transport modeling products for

environmental emergency response and backtracking (CBS) Global Producing Centre for long-range forecast (CBS) Tokyo Climate Centre (CCl/CBS) World Data Centre for Greenhouse Gases (CAS)

JMA continues and improves its operation for international responsibilities in WIS Part A and also implements WIS Part B.

WIS Part A : Improvement of GTS

RTH Tokyo acts as a node between the RAII Regional Meteorological Telecommunication Network (RMTN) and the Main Telecommunication Network (MTN).

WIS Part A : GTS operation at RTH Tokyo

RTH Tokyo operates high-fault-tolerance telecom systems for GTS operation. Well-trained shift operators and technical support experts guarantee its 24/7 operation.

WIS Part B : Integrated infrastructure

JMA is actively working to develop and establish integrated infrastructure of WIS Part B, according to WIS requirements.

WIS Part B : Metadata handling

Creation and Synchronisation Metadata is created/edited via web interface or uploaded by the originator, before synchronised among collaborating GISCs. JMA considers OAI-PMH as the primary candidate for synchronisation protocol. Several tabular forms will be supported for metadata uploading in addition to direct submission of ISO 19139 XML document form. 

Catalogue and Search Metadata collected to GISC Tokyo will be stored in a database for catalogue search. The primary interface of the catalogue search is SRU as required in WIS. Ongoing design work fully considers compatibility with SRU extension of GeoNetwork. It is under consideration to implement gateway to support CSW and ASN.1 Z39.50 protocols.

Browsing Structure of Catalogue It is observed that the hierarchical keywords for browsing structure best suites with observational data, while grid data often has many equally-important search keys (such as forecast time, vertical level, or physical quantity) that does not fit with hierarchical structure. Tabular listing looks promising for this purpose, and JMA will continue study.

WIS Part B : Metadata for bulk data like GRIBs

WIS Part B : Data handling

The WIS Part B system of JMA receives data feed from GTS and will provide the data by both push and pull protocols.

Blog-related technologies   JMA is performing tests to demonstrate the fitness of blog-related technologies as standards for both push and pull protocol.  

Data flows for the file synchronization

WIS Part B : Data handling

WIS prototype service in operation JMA has developed a new data provision system based on a pull mechanism to provide large amounts of via the Internet.

It was introduced to NMHSs in 2007, as JMA‘s WIS prototype service, and has already been implemented on a semi-operational basis through a system in which regular users can retrieve satellite and numerical prediction data through a dedicated web site.

WIS Part B : User management

WIS Part B requires ad-hoc registration and management of users through web interface. DCPCs in JMA will use the same interface for unified user experience of WIS as a system.  Sharing user and role information among many organisations is another challenge. In order to avoid the risk of sharing raw or hashed passwords, distributed authorisation technology is desirable. Standardisation will require careful examination including applicability with many data/metadata transfer protocols. JMA will continue the study.

Collaboration : Collaborative work with other potential GISCs

JMA has been in collaboration with the China Meteorological Administration (CMA) on the WIS development to implement interconnection and interoperation, including metadata exchange and synchronization, remote data request and access between the GISC prototypes at both organizations. The most recent meeting in Sep 2009, which was also attended by the Deutscher Wetterdienst (DWD), had detailed discussion on DAR metadata and metadata synchronization.

Recognizing that some guidelines for WMO core profile is necessary for the effective function of DAR databases, the meeting submitted a report to IPET-MDI and other related bodies for their consideration.

Collaboration : WIS VPN Pilot Project in RAs II and V

Towards the secure exchange of data through the Internet using VPN technology, JMA has being taking a leading role in the WIS VPN Pilot Project in RAs II and V. The project provides participants with an opportunity to step into WIS implementation, and is expected to contribute to the WIS implementation through; i) Technical consulting body on VPN ii) Prototype mechanisms at WIS application level, and iii) Capacity building for participants in WIS semi-operation.

Capacity building : Training courses and technical support

JMA has been providing expert services and training programs to developing countries for decades. In particular, the series of Japan International Cooperation Agency (JICA) group training courses on meteorology includes lectures on telecommunication and data management, and has received more than 250 meteorologists from the National Meteorological Services of developing countries since 1973.

In addition, through the implementation of the Japanese government’s aid programs in the field of meteorology, JMA provides a range of technical support in cooperation with JICA and other national authorities.

Capacity building : Training courses and technical support

JMA visited Bangkok and Manila at the occasion of JMA visited Bangkok and Manila at the occasion of establishing a new MPLS IPVPN network in March 2009. establishing a new MPLS IPVPN network in March 2009.

Capacity building : Training courses and technical support

JMA well recognizes the needs to build capacity in all WMO Members to participate in this important effort, and wishes to further cooperate with NMHSs for the successful implementation of WIS. In this regard, JMA will hold an international workshop: "Towards the successful implementation of the WMO Information System in Asia", in Tokyo on 9 -11 March 2010, inviting 15experts in Asian NMHSs. The main purpose of the workshop is to share with the participants the WIS vision, the technical specifications, the current status of WIS development, etc., to help those NMHSs in contributing to and benefiting from WIS. It is also expected that this workshop will facilitate the identification and consolidation of the requirements related to WIS in Asian countries.
